1) normally use LPF or HPF?
---a) without sub?
---b) with sub?

2) how bout the bass and treeble setting?

i m using 4channel. my setup is
ch1/ch2 - front (component set 6.5)
ch3/ch4 - bridge for sub (not yet buy)

i already tune. just wanted to know how u guys tuning only?

crossover set to full pass if u are using passive crossover

bass - 0
treble - 0

totally dun understand what u mean here. can u answer by number? eg

1. answer 1
1a. answer 1a
1b. answer 1b

2. answer b.....etc

Even if you are running passives, you still need to set to HPF, unless you want your comps to play down as low as 20hz by setting to FULL.
And I have never come across any comps that can play so low.
For the sub, set to LPF.

so normally the front door component are set to HPF rite? for sub defintely LPF.

in ur case, yes

Is usual component set uses HPF setting.

For my setup, i've set HPF at 80Hz to eliminate low bass distort from front door. Leaving my 6x9 to LPF to get the bass sound job done.

If set to Full Pass then you have no sound stage effect.

sound like most of u all set to FULL for HPF for front 6.5 component. then how bout its bass and treeble? got any setting for that? i mean for front component

amps i think normally got bass boost and adjustable gain(volume) onli, no bass and treble config. if u use component, then u juz set full pass and let the passive x-overs do the job.

let me put in simple words

front comps on passives xover...go HPF range within 60Hz to 80Hz, depending on xover order and component character

sub is alwiz on LPH with d xover at regions of 80hz and below.

good amps do not have bass/treble settings
only gain control and xover
top ends prolly dont even have xover and gain...hahahahaha

Btw, for mine, i set my amp to full range with gain at 7o'clock, use HU xover(80hz@18db)...but now im subless....previously using also HU xover for sub(100hz).....

What comps are you using??
Check the FR and if possible, reduce the HPF to 63hz at 18db/oct.
This would give you more ooommmmp in the front stage..

what is FR?

Wrong info

FR=frequency response.
Normally for comps, the manufacturer will state the FR, for example, 50hz-20,000hz.

ok. ya. mine oso stated 50hz-20,000hz. what relation FR and the compo?

FR rating means ur comps runs best at that range

example:

Frequency response 50hz to 20,000Hz....meaning to say ur comps works best within that range

i set my hpf at 63hz @ 12db.

distortions? well probably installations problems.

ok, ysdy i borrow my fren's ear.

i am using 4 channel amp, using 3 stereo method mean ch1 and ch2 for my component set and ch3 and ch4 bridge for subwoofer.


this is what is did:
ch1 and ch2 - HPF
ch1 and ch4 - of coz LPF

all the bass coming out from rear....then can listen the songs more clearly and the sound stage much better.

but sometimes, listening to different song got different tuning....

eg: if i tune nicely to listen soft type (oldies, love songs) then when i switch to techno/rock....it doesnt suit.....

mayb i need to tune until generally can support all range of songs

What are your HPF and LPF settings??
